The Nikon 10-22x50 is a great bang-for-the-buck porro prism binocular, the Action series by Nikon feature knobby rubber armored housings. Their high-refraction prisms feature wide fields of view. And every Action model has a tripod adapter threading for easy extended glassing from a stationary position. The zooming 10-22x50 model is intended for both lowlight viewing at the shorter end of the zoom as well as distant observations in better conditions. This is a full sized binocular at home on a support of some kind, with an incredible range coupled with light-swallowing 50mm objectives.
